Answer:
t ≤ 4.5
Step-by-step explanation:
We are told that the goal is to walk at least 18 miles
She walks at a rate of 4 miles per hour, speed is 4mph
Required
the inequality for the time taken to walk the distance and the said speed
Step two:
we know that
speed= distance/time
time=distance/speed
substitute
time= 18/4
time= 4.5 hours
Time≤ 4.5 hours
We know that the lengths of the two smaller sides have to be more than the third side when they are added together
The third side couldn't be 2 or 3 because 9 (7+2) or 10 (7+3) are not less than 10
The third side couldn't be 17 or 18 because 17 (7+10) is not larger than 17 or 18
The correct answer is C. 4 works because 7+4=11 or more than 10. 16 works because 7+10=17 is more than 16
Hope this helps
